Our committed cruiser casts a critical eye over one of the world's most advanced cruise ships, the newly launched MSC flagship, the 6000-passenger Grandiosa. Words: Roderick Eime
We all know the cruise industry has attracted criticism in recent times for some environmentally unsavoury practices. Whether it is the discharge of wastewater, air pollution or overuse of single-use plastics, the global multi-billion-dollar cruise industry certainly has some questions to answer.
I'm here in Hamburg for the very festive launch of MSC Grandiosa, the brand new180,000 GT, 331m flagship of the world's largest privately-owned cruise line. We are fed and refreshed in regal style as this giant ship is welcomed into the world's luxury cruise fleet and screen idol, Sophie Loren, is on hand as usual for the ribbon-cutting in front of the world's travel media and more than 14,000 travel agents.

But apart from her staggering statistics, the cruise line has integrated some of the latest maritime technology into Grandiosa's design, making her one of the
most environmentally friendly such vessels afloat despite her ample proportions.
Grandiosa is the first of three MSC's Meraviglia-Plus ships, all of which employ state-of-the-art exhaust scrubbers to remove 98 per cent of such harmful emissions as sulphur oxide and nitrogen oxide. As something of a tech geek, I was impressed to learn that extra catalytic converters (similar to those in your car) turn harmful nitrogen oxide into harmless nitrogen gas and water.
While most large cruise ships continue to burn
Heavy Fuel Oil (HFO) at the rate of about 200-250 tonnes per day, others are converting to light marine diesel, a fuel identical to that which we pump into road vehicles. Unlike HFO, it floats and evaporates if spilled and produces much less harmful byproducts when burned. New generation cruise ships currently under construction by MSC and others will employ
Liquid Natural Gas (LNG) exclusively, vastly reducing - but not eliminating - emissions.
“Our focus on innovation since we built our first cruise ships only in 2003 ensures that we have one of the most modern fleets at sea as well as one of the highest environmentally performing, “said Pierfrancesco Vago, MSC Cruises executive chairman in a press conference at the launch, “And, thanks to our long-term planning, this will allow us to already achieve a fleet-wide 29 per cent reduction in carbon intensity (rate) by 2024 vs. 2008, well on our way to meet the 40 per cent reduction target set for 2030.”
We don't need to be mathematicians to work out that
MSC Cruises will not meet its
promised carbon neutral status by January 2020 while continuing to use fossil fuels, so an intensive carbon offset campaign is underway to supercharge their carbon neutrality efforts. Now obviously I haven't audited each of these initiatives, but I can report MSC's stated strategy.
“We will work with leading providers in carbon offsets able to offset CO2 emissions with the highest level of integrity,” said Mr Vago, “Our vision is to also invest in projects that provide quantifiable community benefits, protect the environment and support the UN Sustainable Development Goals.”
From press materials obtained from MSC and my own independent enquiries, I've been able to find out more about these 'green' mechanisms.
No Discharge
One thing I can confidently report is that you won't see any ugly images of MSC ships emptying their bowels into the sea as has been seen elsewhere. All wastewater is processed on board with their Advanced Wastewater Treatment System (AWTS). The system separates solids that are removed from the cycle and treated separately. This bio 'sludge' is dehydrated and compacted into high-grade ‘pellets’ which can either be burned as a fuel source or offloaded to a certified shore facility. Because of their high-grade organic quality, these soil-like pellets can be added to landfills to enhance composting action or even used as agricultural fertilizer. The reverse osmosis filtered and UV-treated water is close to municipal 'tap' quality and is perfectly safe to return to the sea. I'm told that MSC executives even drank the water in a demonstration of its purity. Wish I'd seen that.
Silent Running
As evidenced by my own experience on board, Grandiosa is a silent ship. This is achieved by isolating and insulating the otherwise noisy machine spaces eg engines, generators etc. The massive engines themselves are mounted on 'silent blocks' and the whole space is insulated with sound deadening material. This not only creates a more comfortable space for guests, but also for marine mammals who are bombarded by ship-generated noise. The propellers too have a bubble generating feature that counters the noise created by propellers at full speed.
Slippery Ship
We've seen several new hull designs appear on the scene recently. MSC's state-of-the-art hydrodynamic hulls are not so much revolutionary, but rather a refinement of existing 'bulbous bow' design, where computer modelling has helped create the optimum shape that offers the least water resistance or 'drag'. Like in cars and airplanes, a 'slippery' design allows higher speeds without using extra power and hence emissions. The industry standard 'bulbous bow' is that big round protrusion at the front of a ship that sits below the waterline and guides the water around the hull, greatly reducing the engines' effort in propelling the vessel, hence less fuel consumed and less emissions produced. Non-toxic anti-foul paint is also used on the hulls to prevent marine growth build-up.
Power Play
All ships generate their own electricity using generators powered by the same fuel as used by the engines. Obviously, the less work these engines need to do, the more efficient and the cleaner is the whole package. In the case of most modern cruise ships, the main engines are used to generate electricity for the electric motors that drive the propellers. These propellers are housed in massive rotating pods (Azimuth Pods or just 'azipods') beneath the stern that removes the need for old-fashioned rudders and makes the ships much more maneuverable, especially at low speeds when docking. If Titanic had installed azipods, there's a good chance she would have dodged that iceberg!
Other power-saving measures include ultra-low-power LED lighting throughout the ship and intelligent air-conditioning that monitors interior temperatures and redistributes heat instead of regenerating it. The 26 intelligent elevators fascinate me too. You select your floor and the next elevator is indicated. The computer system optimises elevator movements, vastly reducing wait times and minimises unnecessary lift travel.
One of the topical issues with ships in port is their burning fuel while berthed. While most modern ships have the emission controls already discussed, it nevertheless is beneficial if ships can switch off their oil-burning generators while in port. All MSC ships are shore power ready, meaning they can 'plug in' just like you would do with a caravan at a powered site. The problem is, as I've discovered, is that there are only about two dozen ports in the whole world able to offer shore power to cruise ships. This is a complex discussion for another time, but obviously needs to be addressed.
Plastic Fantastic
It seems every day there are heated discussions and finger-pointing in regards to plastic reduction, disposal and recycling. MSC and the other big lines are feeling consumer and regulatory pressure and responding – some more effectively than others. From my own superficial investigations, MSC does not yet have a perfect scorecard, but I'm pleased to report many of the most offensive single-use plastics like straws, cutlery and bottles are almost gone. Almost.
MSC have instituted many procedures to deal with this waste sensitively for example, I was told that the supply chain was intimately examined to identify where waste can be reduced if not eliminated. For example, many of the bulk cleaning liquids and detergents used behind the scenes are now delivered as solid concentrate, eliminating hundreds of tonnes of plastic packaging in one fell swoop.

Of particular note is MSC's concern with the health of the oceans. To this end, they are embarking on projects which protect and restore ocean and coastal habitats while also absorbing more CO2 than current levels. These so-called Blue Credits are earned by dealing directly with the health of our seas and rivers, bearing in mind that the ocean is a very efficient absorbent of atmospheric carbon dioxide, accounting for the absorption of more than one-third of human-caused emissions thus far.
To this end, MSC in conjunction with marine biologists and conservationists, are rejuvenating a derelict sand mining island in the Caribbean, to be called
Ocean Cay, turning it into a marine sanctuary that guests can enjoy during their cruise as an enriching shore excursion.
Geek Solutions and Tech Fun
Aboard ship, numerous hi-tech features makes guests' experience more enjoyable including Zoe, the virtual assistant that keeps tabs on your schedule, bill and children; smart elevators that direct you to the next elevator going your way; extensive adults and children's entertainment including a full-size F1 simulator and head-spinning VR games – all of which could easily be the subject of their own feature.
In summary, when you add in superior dining and guest service levels, well-appointed cabins and suites as well as class-leading theatrical shows including the only Cirque du Soleil at Sea, you have very near the perfect combination of features for the best possible cruise experience. But hey, don't take my word for it.
